Beating Heart Cadaver
A beating heart cadaver is a body that is pronounced dead in all medical and legal definitions, connected to a medical ventilator, and retains cardio-pulmonary functions. This keeps the organs of the body, including the heart, functioning and alive. Roach, Mary. ''Stiff: the Curious Lives of Human Cadavers''. New York: W.W. Norton &, 2003. Print. As a result, the period of time in which the organs may be used for transplantation is extended. The heart contains pacemaker cells that will cause it to continue beating even when a patient is brain-dead. Other organs in the body do not have this capability and need the brain to be functioning to send signals to the organs to carry out their functions. A beating heart cadaver requires a ventilator to provide oxygen to its blood, but the heart will continue to beat on its own even in the absence of brain activity. This allows organs to be preserved for a longer period of time in the case of a transplant or donation. A small number of cas ...

Intensive Care Unit
An intensive care unit (ICU), also known as an intensive therapy unit or intensive treatment unit (ITU) or critical care unit (CCU), is a special department of a hospital or health care facility that provides intensive care medicine. An intensive care unit (ICU) was defined by the task force of the World Federation of Societies of Intensive and Critical Care Medicine as "an organized system for the provision of care to critically ill patients that provides intensive and specialized medical and nursing care, an enhanced capacity for monitoring, and multiple modalities of physiologic organ support to sustain life during a period of life-threatening organ system insufficiency." Patients may be referred directly from an emergency department or from a ward if they rapidly deteriorate, or immediately after surgery if the surgery is very invasive and the patient is at high risk of complications. History In 1854, Florence Nightingale left for the Crimean War, where triage was used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Curious Lives Of Human Cadavers
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'' ...

Legal Death
Legal death is the recognition under the law of a particular jurisdiction that a person is no longer alive. In most cases, a doctor's declaration of death (variously called) or the identification of a corpse is a legal requirement for such recognition. A person who has been missing for a sufficiently long period of time (typically at least several years) may be presumed or declared legally dead, usually by a court. When a death has been registered in a civil registry, a death certificate may be issued. Such death certificate may be required in a number of legal situations, such as applying for probate, claiming some benefits, or making an insurance claim. Medical declaration Most legal determinations of death in the developed world are made by medical professionals who pronounce death when specific criteria are met. Two categories of legal death are death determined by irreversible cessation of heartbeat ( cardiopulmonary death), and death determined by irreversible cessation of ...

Heart Transplantation
A heart transplant, or a cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure when other medical or surgical treatments have failed. , the most common procedure is to take a functioning heart from a recently deceased organ donor (brain death is the most common) and implant it into the patient. The patient's own heart is either removed and replaced with the donor heart ( orthotopic procedure) or, much less commonly, the recipient's diseased heart is left in place to support the donor heart (heterotopic, or "piggyback", transplant procedure). Approximately 5,000 heart transplants are performed each year worldwide, more than half of which are in the US. Post-operative survival periods average 15 years. Heart transplantation is not considered to be a cure for heart disease; rather it is a life-saving treatment intended to improve the quality and duration of life for a recipient.

Clinical Death
Clinical death is the medical term for cessation of blood circulation and breathing, the two criteria necessary to sustain the lives of human beings and of many other organisms. It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest. The term is also sometimes used in resuscitation research. Stopped blood circulation has historically proven irreversible in most cases. Prior to the invention of cardiopulmonary resuscitation (CPR), defibrillation, epinephrine injection, and other treatments in the 20th century, the absence of blood circulation (and vital functions related to blood circulation) was historically considered the official definition of death. With the advent of these strategies, cardiac arrest came to be called ''clinical death'' rather than simply ''death'', to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brain Stem Death
Brainstem death is a clinical syndrome defined by the absence of reflexes with pathways through the brainstem – the "stalk" of the brain, which connects the spinal cord to the mid-brain, cerebellum and cerebral hemispheres – in a deeply comatose, ventilator-dependent patient. Identification of this state carries a very grave prognosis for survival; cessation of heartbeat often occurs within a few days, although it may continue for weeks if intensive support is maintained.A Code of Practice for the Diagnosis and Confirmation of Death. Academy of Medical Royal Colleges, London, 2008 In the United Kingdom, death can be certified on the basis of a formal diagnosis of brainstem death, so long as this is done in accordance with a procedure established in "A Code of Practice for the Diagnosis and Confirmation of Death", published in 2008 by the Academy of Medical Royal Colleges. The premise of this is that a person is dead when consciousness and the ability to breathe are pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confucianism
Confucianism, also known as Ruism or Ru classicism, is a system of thought and behavior originating in ancient China, and is variously described as a tradition, philosophy, Religious Confucianism, religion, theory of government, or way of life. Founded by Confucius in the Hundred Schools of Thought era (c. 500 BCE), Confucianism integrates philosophy, ethics, and social governance, with a core focus on virtue, Harmonious Society, social harmony, and Filial piety, familial responsibility. Confucianism emphasizes virtue through self-cultivation and communal effort. Key virtues include ''Ren (philosophy), ren'' (benevolence), ''Yi (philosophy), yi'' (righteousness), ''Li (Confucianism), li'' (propriety), ''Wisdom, zhi'' (wisdom), and ''Xin (virtue), xin'' (sincerity). These values, deeply tied to the notion of ''tian'' (heaven), present a worldview where human relationships and social order are manifestations of sacred moral principles..

Brain Death
Brain death is the permanent, irreversible, and complete loss of Electroencephalography, brain function, which may include cessation of involuntary activity (e.g., Control of ventilation#Control of respiratory rhythm, breathing) necessary to sustain life. It differs from persistent vegetative state, in which the person is alive and some autonomic functions remain. It is also distinct from comas as long as some brain and bodily activity and function remain, and it is also not the same as the condition locked-in syndrome. A differential diagnosis can medically distinguish these differing conditions. Brain death is used as an indicator of legal death in many jurisdictions, but it is Medical definition of death, defined inconsistently and often confused by the public. Various parts of the brain may keep functioning when others do not anymore, bringing questions about whether they should truly be considered dead. The term "brain death" has been used to refer to various combinations. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
